The exactness and stability of the Wilkins method in the investigation of the stress-strain state of axisymmetric anisotropic elastic shells, including thick-walled ones, have been studied for different values of artificial viscosity, pulse load rise and fall time, and different deformation process durations. A comparison of numerical calculations, performed by means of an application software package developed by V. A. Romashchenko on the basis of the Wilkins method, with experimental results, known numerical data, and with calculations using the computation kernel LS-DYNA 3D has been carried out. 相似文献

The Wilkins two-dimensional algorithm-based method of numerical studies on the dynamic behavior of multilayer thick-walled cylindrical shells with different spiral reinforcement structures is developed. Test calculations are in good agreement with known solutions. The dynamic behavior of a two-layer cylinder with different spiral reinforcement structures is investigated.Translated from Problemy Prochnosti, No. 6, pp. 99–110, November–December, 2004 相似文献

Modification of the Wilkins method has been performed for numerical investigation into dynamics of thick-wall cylindrical shells with a spiral orthotropy. Test calculations are shown to agree well with the known solutions. New physical effects have been found, which are absent from isotropic and cylindrically orthotropic bodies. 相似文献

The analytical solution is obtained in quadratures of the elastic theory dynamic centrally-symmetric boundary problems of
the same class for multilayer transtropic spheres, the sonic speed in the radial direction of which tends to infinity. Convergence
and accuracy of the derived solutions are analyzed. It is shown that the analytical solutions obtained can be used as the
first approximation for the cases where the sonic speed in materials is finite. 相似文献
